Need help( Gx Developer 8)

Towerlight · Apr 5, 2010

Hi All,

Does anyone know about Gx Developer 8?
If a Input is activate and i want to display the time the Input is activate on my HMI.
How to i write the program?

Thanks

What is the HMI? GX is for the PLC... so you need the HMI program not the PLC, then you just make a indicator light and address that to change states in the HMI

Green X0 = on
Red X0 = off

Hi Geniusintraining,

The HMI is Human Machine Interface(Touch Screen). When the input is activate,
i want the HMI to display the total hours/minutes that the Input is activate.
Anyway the HMI i'm using is the Pro-Face GP3000 Series.

Thanks

In your PLC you will need a timer/counter, then in the HMI you will need to make a tag with that address... I have never used Pro-Face before

Hi Geniusintraining,

Thanks for reply, I not sure what function i can use in Gx Developer 8 to make hours/minutes. Hope you can help.

Thanks

Not sure how accurate you need to be or what CPU you have... but look at SM412, this is a 1 second internal bit and will turn on and off every second, you can use this with your input then have that go to a counter

[input]-----[SM412]-----(counter)

Then have the couter displayed in the HMI, you will also need a button or something to reset, if you need it in min have the first counter count to 60 then start another counter, then you have min/input/on

clear as mud?

Hi Geniusintraining,

What is the SM412? I'm using the Q Series QnU CPU Ethernet.

Thanks

see attached, you can also search your help file in GX

Hi Geniusintraining,

The Pro-Face touch screen does not have a C address.
They have X, Y, M, SM, L, F, V, S, B, SB, TN, SN, CN, D, SD, W, SW, R & ZR.

Thanks.

Make a move in the PLC to a place that the HMI can read...

The pic below is moving D0 to K2Y000, this is a output word so don't use that address but find one that you can use in your PLC that your HMI can read, maybe you can use a M that is not being used in the rest of your program

Instead of using a counter - increment a D register,that way the Proface unit could read that directly.

Example: Q series instructions

D0 - Counter
M0 - Trigger - change to your Input

Code:

  M0       SM412
--| |-------| |---------------[+P K1 D0 D0]

Oh sure... now you come 3 days later and post some fancy code and look like the hero

Towerlight, as you can see we all help each other.... STL's idea is better and cleaner

clean code is good code :nodi:

Regards!

Thanks Geniusintraining & STL???

But how to i key in the +P K1 D0 D0?
Can you also explain how the +P K1 D0 D0 works?

Hi Mark

Towerlight,

To enter the instruction into the editor i press key F8 which gives me an 'enter symbol' dialog, then type in the instruction as above(without brackets[])

[+P K1 D0 D0] means the following,

+P = ADD instruction with rising edge pulse
K1 = Amount you want to add
D0 = Source register
D0 = Destination register

So each rising edge of the monitored signal add 1 to D0.

Mitsubishi Help file

Adds 16-bit BIN data designated by (D) to 16-bit BIN data designated by (S) and stores the result of the addition at the device designated by (D).

Hope this helps
